of the machine.

The mechanism through which this is accomplished, described at length,is as follows ZThe cutting ofthe blank is preparatory to the use of theblank with this machine, the pasting of it or the gluing of it isaccomplished at the tank V by pushing the blank manually under thecoating wheel 84 which is driven by a belt 85 from belt wheel 86 on theshaft C. The glue coating appliance, while an adjunct to the machine,forms, as to structural details no part of the invention, and need notbe described. The coated blank is moved manually across the table 1 ontoa plate this plate 65 is a reciprocating sheet metal table or thintablet located on the stem of the die 3; the die 3 reciprocates, drivenby mechanism that will later, and in its backward redraws the thin plate65 from is heldagainst travel, in this direction, with the table byfingers 8 that hang from the frame 60; the lower ends of these fingers 8project into grooves 65 in the plate 65 below the lower surface of theblank 66.- The frame 60 rises above the main frame-work of the machineand is braced by a gooseneck brace 61 from the main part of the machineon therear side thereof, and rises directly from the supports of thetable 1 at the front of the machine. Itsupright axis is inclined fromthe vertical, and it carries and guides a second frame whichreciprocates on the inclined axis; this second frame 62 is normally heldin its most elevated position by springs 64 that surround posts thatrise from the reciprocating frame 62. The reciprocating frame carrieslungers 4 normally lifted by springs 4 and positively forced downward bya lever 78 ultimately driven by a cam on the shaft 45, and driventhrough an interposed .rock lever 79 and a link 78. When the frame 62 isdrawn downward lever 78, it brings the rod 4, which may be considered asa presser foot or as presser feet, for there are two of them, againstthe blank 66, and pushes the blank 66 against the die 3, the frame 62continues its downward motion, being forced downward by the arm 78. Asystem of toggle links pivoted tothe frame 62 and to the presser foot 4actuate a three part folding frame, 2, 2* and 2 of which-the centralpart 2 of about 120 degrees are is fixed to the plate 63, which formsthe base of the frame 62; the parts 2 and 2 each of which comprise about120 degrees are hinged to the part 2 at its edges and are connected bytoggle links to the frame and to the presser feet. One of the links 6 islonger than its companion link 5,

ciprocation and is actuated b /a link 6 in the system of the die 3 isshown as by the i the other part presses, and this insu i'es thecertainty of folding that edge of the blank which is under the Wing 2under thatedge of the blank which is under the wing 2 and always bringsthe glued surfaces together; generally, the glued surface is along thatedge of the blank which is under the wing 2 and thus the glued surfacelies to the outside of the die 3 on the partially folded blank beforethe edge under the wing 2 comes into intimate connection with it. Theiblank folded around the die 3 now advances with the die into the matrixdie; the advance of the die is effected by means of thettoggle levers,shown in detail in Fig. 3, 'inEwhich projecting from a reciprocatinghead 11 that travels on tie rod 58, which rod forms the axis of thehead11, and also the axis .upon which the matrix dies 7 revolve. The head 11is held to a fixed head 57 by toggle levers 55 and 56 and these togglelevers 55 and 56 are actu-, ated by crank arms 53 and 54 from the cranks51 and 52 upon disks 49 andi 50 at the head of the shafts E and F, whichare driven, as has been heretofore stated, ultimately by the shaft A andmore directly by the interposed shafts and gearing that has beenheretofore described. 7

The toggle system affords ,an extremely strong pressure of the die 3 andthe matrix die 7 the connection betweenthe links 54 and 53 with thetoggle links is made with lost motion joints which produce anintermitting action of the toggle levers and an intermittingreciprocating of the head 11 rom a constantly rotating motion of thecrank pins 51 and 52. Shock is obviated by air dash pots 59 whichconnect the toggle joints and the head 57., During the advance of thedie 3, the air is drawn out therefrom by air suction through pipe 67through the valve-'68 in the casing 68, which valve is a four-way valvearranged to convert suction into blast by turning the valve in thecasing 90 degrees. The pipes 69 and 70 are in circuit with an aircompressor the valve in case 68 being turned by levers 86 actuatedultimately by a cam on the cross shaft K. The lever 86 which actuatesthe link 71 is pivoted to the frame, and is lifted by the cam on thecross shaft K, lifting the link 71 and turning the valve 68* in thecasing.

Suction action is maintained during the folding of the blank around thedie 3, during the advance of the die 3, and until the final pressureaction of the die 3 against the matrix die 7, blast action forces theblank from the die before the retreat of the die 3; the turret headcontaining a number of dies 7 is revolved until the die 7 containing theblank which has just been treat-' ed reaches the end turning location.The end of the now partially finished bottle is turned in so as todouble the end in on the body of the bottle at the small end of thebottle, and this is done by a' plung'eractuated by the lever 18, shownin Fig. 2. The lever 18 is actuated by a cam on the shaft C which turnsagainst an anti-friction wheel 18 at the bottom of the lever 18; theupper end of the lever 18 is linked to.a plunger shown in Fig. 13. Theplunger reciprocates and the main body 17 of it'rotates on itslongitudinal axis, being joined by coupling 80 to the link 81, whichcoupling 80 is provided with trunnion pins 82 to which the linkconnects, and it contains the end of the headed shaft 17. The shaft 17is provided with a spline'and slides through a pulley 20 driven from apulley wheel on the shaft A; the pulley rotates the shaft 17 The pulley20 is held from undesired movement lengthwise of its axis, which mightotherwise be caused by the friction of the shaft 17, which passestherethrough, by the overreaching bracket arm 22. The shaft 17 carriesat its forward end a head that enters the matrix die 7 at the smallendthereof, and a centering projection 17 b on the head enters a centeringhole in the anvil die or holder 10 that 'advances into the die. from thelarge end thereof simultaneously with the entrance of the die 3 into anewly forming bottle.

The die 10 does not reach to the extreme end of the blank, leaving aprojecting part 65 of the blank 66 to be turned in against itself. Thehead 14 at the end of the shaft 17 is provided with the centeringprojection 17 with acollar, 15 upon which there is a turning finger 16,-the front edge of which is slightly inclined to the ,line of the collar15 and projects at the side thereof, and is slightly undercut or curvedalong that face which contacts the edge of the bottle blank 66, and whenrotated and at the same time pressed against the edge, turns the edge inon itself until the bottle end finally assumes the form shown in Fig.15.

The head 14 is held out toward the end .of the neck 17 of the shaft 17by a spring 23 which presses the head against the limiting collar 25; Afeather 24 compels the head to turn with the shaft; after the edge hasbeen turned, the anvil die 10 and the plunger 17 both withdraw; theturret head advances a step, and an expelling plunger 27 enters thesmall end of the matrix die and expels the bottle from the die onto thetrough 29; the ex elling head is actuated by a lever 40 .to beautomatically pro ected by which is oscillated by a cam on the shaft C,and is provided at its expelling end with a projectile head 28 held in acavity in the shaft 27 against a sprin 35, and arranged the force ofthespring and retracted into the cavity by the retreating action of theplunger 27. Apin 38 passed through the walls of the plunger 27 andthrough an elliptical'opening in the head 28 limits the outward movementof the head 28; a pin 33 engaging through a trigger 31 that is pivotedto a hanger from the walls of the plunger 27 retracts the head into itscavity when the tail 31 of the trigger 31 engages a projection 41 on theframe, through which the plunger 27 reciprocates. The top end of'thetrigger 31 is caught under a hook 36 that is disengaged from the triggerwhen the plunger 27 has advanced to bring the angle arm 36 of the hookagainst a hanger 32 on the frame; the hanger 32 is adjustable by meansof adjusting screws 32*. The engagement between the angle arm 36 and,the hanger 32 acts substantially at the end of the forward movement ofthe plunger 27, andthis engagement is immediately forced by the suddenprojection of the head 28 which ives to the already loosened bottle aproectile force that throws the bottle clear from the matrix 7 onto thetrough 29 and in front of a hook 30 carried by the die 10. This hook 30is pivoted and is lifted against a stop 30, and at the close of theforward movement of the die 10 the head end of the hook 30 is forceddownward by engaging against the part of the frame or the hanger 30hanging of the hook lifts as soon as the plunger 10 retreatssufliciently to allow it to do so, engages trough 29, engages the bottleinthe trough and carries it and any bottle which may be in fro nt of itforward toward the delivery end of the machine. A I

The hollow die members are in a turret head carried on the shaft 58.This turret is revolved by a system of actuating pawls shown in detailin Fig. 10, which supplementsFig. 2 on which the main actuating thrust.

The pawl 88 simply engages in the notch 91, in which it is held by aspring 92. At times when the tension of spring 93 does through a slot inthe bottom of the from the trough 29. The bill forced upwardly into thenotch in the turret due to the movement of the link 94 and of thepivoted lever 94 under thedownward pull of the lever 94; when the cam 74revolves to present the high part thereof under the arm 94, the link 94is thereby caused to rise and push upwardly the opposite end 5 of thelever 94 from that to which the pawl 88 is connected, thus forcing thepawl 88 downwardly against the resiliency of the spring 92, and causesits disengagement from the notch contemporaneously with the release ofthe pawl89 from engagement with the notch 96; the turret is then freeto. re-

volve and does revolve on its axis.

During the period of disengagement of the pawl 88 with the turret, thepawl 89 which has ,a head yieldingly projected by the spring 7 5 is alsodisengaged from the notch 96 by the interaction of its driving lever 97and the cam 76. The spring'projected head 89 coacts with the pawl 88,the one being fixed in position and the other under spring tension togive to the turret head a backward torque which holds it properlycentered. The sliding head 11 is provided with a notch on its under sidewhich engages on a track 99 which holds it from turning.

As an additional safety means to prevent the closing in of the head 57against the bearing or block 101 through which the shaft 58 extends, arod 102 is placed between the head 57 and the block 101, the mainpurpose of this being to prevent the bearing 58 from being drawn out ofits holding connection with the head 57 What I- claim is 1.
